Application filed July 16,

To f/Z/ l/f/mni 'it may Concern Be it known that I` L 'F. FULLER` a citizen of the nited States. residing at Terry, in the county of Hinds and State of Missisl sippi. have invented new and useful .Ini-

prorements in Fishplate and ut Locks, of which the following is a specification.

The object of this invention is to pro.

ride a special type of fish plate with which a nut retaining device directlyv cooperates A Jfurther object is to provide a fish plate having a longitudinal flange, or fianges. end portions, and an expansiblc bar extending between one of said flanges and the nuts carried'by the usual bolts securing the rails.

lVith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of' elements described and claimed, it being understood that modifications may be made Within the scope of the claims without departing from the spirit of the invention.

In the drawings, Figure l shows the fish Q is a vertical transverse section through two fish plates and a rail; Figure 3 isI a` perspective view of a form which maytbe rolled or stamped from sheet metal; Figure 4 is :i perspective view ot the lockingjbar.

.In carrying out the invention I provide a fish plate 10. shown in Figure 1 as being of heavy metal, and shown at 10 in Figure 3 as being of sheet or rolled metal. The plate includes end portions 11 and 12 disposed perpendicularly with reference to the web and is provided with bolt holes for the bolts 13 retained by nuts 14.

A locking bar 15 is of channel form, the web of the channel being against the web of fish plate 10, and the ends of the channel plate and nut lock in side elevation; Figure' 1923. serial No. 651,961.

bar passing through openings 18 in end members 11 and 12, any suitable retaining device or devices being employed.

The flanges ot element 15 are bent outwardly to engage the nuts 14 and the base fiange of fish plate 10, this spreading er expansion of locking bar 15 preventing the loosening of the nuts.

In the modification of Figure 3, the fish plate 10 of rolled metal is shown as having one end bent at right angles with the web` and both ends are provided with apertures 18 for the channel bar 15. which is inserted after bolts 13 and nuts 14 have been applied in the usual manner.

After passing bar 15 through openings 18, the anges may be flared to engage respectively the nuts, (or some of them), and the lower flange of splice bar 10. The ends of element 15 may be secured to the splice bar in any obvious manner.

By the use of either form of this device, the nuts are securely retained until inten. tionally loosened b v withdrawing the bar.

What is claimed isz- 1. The combination with a fish plate, comprising a web, lower flange. and end members` of an expansible locking bar, to be passed through said end members and contact with the lower flange, and adapted to engage the nut of a bolt to be passed through the fish plate.

2. The combination with a fish plate, comprising a web, lower fiange, and end mem- 76 bers, of an eXpansible channel shaped locking bar, to be passed through said end members and contact with the lower flange, and adapted to engage an element for securing the fish plate.

In testimony whereof I affix my signature.
